Shell composition and capsule using the shell composition
Provided is a shell composition that is formed with a water-insoluble powder such as starch and/or a water-soluble polymer such as dextrin as a base component, and with locust bean gum and/or xanthan gum as a gelling agent. This shell composition enables a novel shell composition which can favorably form a shell without using carrageenan, has favorable properties that enable the shell composition to substitute traditional shells that use a gelatin shell or carrageenan, and comprises a plant-derived base.
